A 10-year-old girl presented with a brainstem epidermoid cyst manifesting as dysphagia and postprandial vomiting. Magnetic resonance imaging disclosed a cystic mass in the brainstem with associated hydrocephalus. She was treated under a presumptive diagnosis of abscess until the definitive histological diagnosis was established at the fourth admission. In spite of four interventions, she remained in good condition with minimal cranial nerve pareses. Subtotal removal of the epidermoid cyst in the brainstem results in recurrence within a relatively short period, especially in children. Total resection of the tumor is the optimum treatment. The differential diagnosis includes abscess, cystic glioma, and neurenteric cyst.

“…In the literature, DWI sequences greatly aided in the evaluation of the postoperative patients. On conventional MRI, postoperative changes in the surgical cavity usually make the detection of residual tumor or recurrence more difficult (9). In our cases, post-surgical follow-up MRI studies, including DW and FLAIR imaging, showed no residual tumor or recurrence.…”

Epidermoid cysts (ECs) are benign, slow-growing, congenital tumors. Intracranial ECs usually localize in extra-axial spaces, particularly in the cerebellopontine angle or in the parasellar region. Their occurrences in the fourth ventricle or intradiploic location are exceptionally rare. We present the imaging findings in two patients with atypical localization of ECs. Magnetic resonance imaging (MRI) findings for the first case revealed an intraventricular EC, and the second case demonstrated an EC that invaded into the intradiploic spaces and the calvarium. Conventional MRI, including T1 and T2 weighted imaging (T1WI and T2WI), may not always differentiate ECs from other cystic intracranial lesions. In addition to conventional MRI findings, diffusion-weighted imaging (DWI) and fluid attenuation invention recovery (FLAIR) sequences play an important role in the differentiation of ECs from other intracranial cystic lesions, thereby reflecting the contents of the lesions. In conclusion, we recommend the use of FLAIR and DWI sequences in addition to conventional MRI sequences for the differential diagnosis of the atypical localized epidermoid tumors.
